CHURN-DASHER.

Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed September 20, 1906. Serial No. 335,470.

To (I/ZZ whom it may concern:

Be it known that I, EDWARD A. FRANKLIN, a citizen of the United States,residing at North Chicago, in the county of Lake and State of Illinois,have invented a new and useful Churn-Dasher, of which the following is aspecification.

This invention relates to churns, and more particularly to a rotarydasher for use in connection therewith.

The object of the invention is to provide a rotary dasher of novelconstruction which will agitate the contents of the churn in a thoroughand efficient manner, and thereby expedite the formation of butter.

,A still further object is to provide a dasher which is of durable andcompact construction and which will not splash the contents of thechurn.

WVith the above and other objects in view the invention consists ofcertain novel features of construction and combinations of parts, whichwill be hereinafter more fully de-.

scribed, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings, Figure 1 is a perspective view of the churn, a portionthereof being broken away to show the dasher. Fig. 2 is a plan view ofthe dasher. Fig. 3 is a vertical section therethrough, and Fig. 4 is abottom view of the central portion of the dasher.

Referring to the figures by characters of reference, 1 is a base havingstandards 2 extending upward therefrom and connected at their upper endsby a cross-strip 3 of suitable contour and provided with depending arms4. A churn-body 5 is arranged upon the base, and journaled in one of thestandards is a short shaft 6, having a drive-gear 7 at its inner end anda crank 8 or other operating device at its other end. The gear 7 mesheswith a small gear 9, secured upon a shaft 10, which is journaled in oneof the standards 2 and one of the arms 4. A beveled gear 11 is securedupon the shaft 10 and meshes with a gear 12, secured, by means of aset-screw 13, upon a rod 14, which is journaled at opposite ends in thebottom of the churn-body 5 and in the cross-strip 3.

The dasher used in connection with this churn is secured upon the rod 14and comprises a tubular core 15, adapted to receive the rod 14 andhaving a set-screw 16, where by said core may be secured in adjustedposition upon the rod. A collar 17 extends around the lower portion ofthe core, and oppositely-extending fingers 18 also project from the coreat points slightly removed from the collar. the lower portion of thecore and has oppo sitely-disposed slots 20 therein adaptedto slip overthe fingers 18, so as to enable the plate to bear against the collar 17.Said plate is gradually thickened adjacent the center thereof, as shownat 21, and said thickened portions constitute Wedges for clamping theplate 19 between the collar 17 and fingers 18 when said plate is rotatedin one direction. tightened together in this manner a pin 22 is insertedthrough the plate and across one of the fingers, so as to prevent theplate from turning back to its initial position and becoming detached.may be soldered to the plate after the parts have been assembled, or thesolder may be used in conjunction with the pin.

Extending from the plate 19 at regular intervals is a plurality ofradial blades 28,

which are bowed rearwardly with respect to the direction of rotation andare twisted or tilted vertically so as to present inclined faces to thematerial to be agitated. Oppositely-extending wings 24' project fromeach blade adjacent its free end. The upwardlyeXtending wings 24 aresoldered or otherwise secured to the inner surface of a band 25, whichrests upon the end portions of the blades, and the lower wings 24 arealso secured to a band 26, which contacts with the lower edges of theend portions of the blades and is similar to the band 25. Both bands arepreferably formed of sheet metal having their edges turned in to formreinforcing- 5 heads 27. These bands serve to hold the ends of theblades firmly braced, and the openings formed between the bandsfacilitate the agitation of the contents of the churn. The end portionsof the blades project between and blades, a portion of said contentsbeing drawn between the bands, while another portion thereof is thrownoutwardly by the projecting ends of the blades. As a result of i .thevarious movements which are simultaneously produced by employing adasher of no A plate 19 is arranged upon 60 After the parts have been 70If preferred, the fingers 75 this construction the churn is renderedvery efficient, because the a itation produced is such as to quickly andt oroughly form but ter.

The preferred form of the invention has been set forth in the foregoingdescription; but I do not limit myself thereto, as I am aware thatmodifications may be made there in without departing from the spirit orsacrificing the advantages thereof, and I therefore reserve the right tomake such changes as fairly fall within the scope of the claims.

What is claimed is 1. A rotary churn-dasher comprising a tubular core,similar bowed and inclined blades radiating therefrom, and similar bandssecured upon opposite edges of, and spaced apart by the blades, the endsof said blades extending beyond the peripheries of the band.

2. A rotary churndasher comprising a tubular core, inclined bladesradiating therefrom, oppositely-extending wings upon the blades, andbands surrounding the wings and secured the eto, said blades serving tospace the bands apart and projecting beyond the peripheries thereof.

8. A rotary churn-dasher comprising a core, bowed, inclined bladesradiating from the core, oppositely-extending Wings upon the blades, andbands surrounding and secured to the wings, said blades projectingbetween and beyond the peripheries of the bands.

4. A rotary churn-dasher comprising a core, an annular collar thereon,oppositelyextending fingers adjacent the collar, a plate rotatablymounted between the collar and fingers, said plate havingfinger-receiving openings, means upon the plate for wedging said platebetween the collar and fingers, means for preventing rotation of theplate upon the core, and inclined blades radiating from the plate.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
